NPCs with their own interests and goals will help you along the way, if you allow them to. From just giving you information and selling you supplies, to giving you quests to earn money and experience points, NPCs play an important role in the game. Below is a list of the NPCs you will encounter along the way--minus any bosses and major spoilers--giving you what Act they are in, where they can be found and what quest or job they have in the game.
